For this edition of his long-running radio show Late Lunch With Out To Lunch, Ben Watson coined the term "aural trace": improvising to music while wearing headphones so listeners cannot hear the original. Originally pioneered to provide a bass track for a live-in-studio cover of Sun Ra's "The Cosmo-Fire" by OTL and Iris, there are aural traces here of two tracks that demand to be heard together: Mint Douche's "Jeezuz'N'God" from Home Recording Is Killing Music (2016) and John Coltrane's "Out Of This World" from Coltrane (1962). The in-studio musicians (Peter Baxter - drums; Out To Lunch - mouthnoise, piano, rattle) respond live to OTL's aural-trace recordings (a vocal response to "Jeezuz'N'God"; and a Yamaha keyboard response to "Out Of This World"). Baxter's poem "Straight Outta Somers Town" becomes lyrics for a sub-Beefheart track; OTL reads "Cartoon" from J. H. Prynne's new publication Each To Each; andrecites a romantic winter email from Michael Tencer. The tapes from the AMM All-Stars at Cafe Oto 12-i-2017 recorded by Simon Peter Holliday are raided, so you also get to hear Jair-Rohm Parker Wells on bass guitar; Len Massey on Theremin; Helen Tate on violin; Paul Shearsmith on hosepipe didjeridoo, squeakers and trumpet; John Plant on "Somehow". Special guests Iris and Mordecai speak out on teeth and Banquo, and there's an airing of "I Don't Want My Body" by the Piranhas (1980). Resonance studio engineer: Adam Barkley. Cover model: Ben Moran Healy.
